Abstract

The present invention relates to an electrode for electrolysis, a laminate, a wound body, an electrolyzer, a method for producing an electrolyzer, a method for renewing an electrode, a method for renewing a laminate, and a method for producing a wound body. An electrode for electrolysis according to one aspect of the present invention has a mass per unit area of 48 mg/cm2 or less and a force applied per unit mass-unit area of 0.08 N/mg·cm2 or more.

1 . A method for producing a new electrolyzer by arranging an electrode for electrolysis or a laminate of the electrode for electrolysis and a new membrane in an existing electrolyzer comprising an anode, a cathode that is opposed to the anode, and a membrane that is arranged between the anode and the cathode,
 wherein the electrode for electrolysis is provided to have a mass per unit area of 48 mg/cm 2  or less and a force applied per unit mass-unit area of 0.08 N/mg·cm 2  or more.   
     
     
         2 . The method for producing the new electrolyzer according to  claim 1 , comprising retaining the electrode for electrolysis or the laminate in a wound state. 
     
     
         3 . The method for producing the new electrolyzer according to  claim 1 , comprising releasing the wound state of the electrode for electrolysis or the laminate. 
     
     
         4 . The method for producing the new electrolyzer according to  claim 3 , comprising arranging the electrode for electrolysis or the laminate on a surface of at least one of the anode and the cathode after releasing the wound state of the electrode for electrolysis or the laminate. 
     
     
         5 . A method for renewing an existing electrode by using an electrode for electrolysis,
 wherein the electrode for electrolysis is provided to have a mass per unit area of 48 mg/cm 2  or less and a force applied per unit mass-unit area of 0.08 N/mg·cm 2  or more.   
     
     
         6 . The method for renewing the electrode according to  claim 5 , comprising retaining the electrode for electrolysis in a wound state. 
     
     
         7 . The method for renewing the electrode according to  claim 5 , comprising releasing the wound state of the electrode for electrolysis. 
     
     
         8 . The method for renewing the electrode according to  claim 7 , comprising arranging the electrode for electrolysis on a surface of the existing electrode after releasing the wound state of the electrode for electrolysis.
